To find an equal ratio, you can divide or multiply by the same number on the top and bottom of the fraction. For example...
<u>5 x 2</u> = <u>10</u>
7 x 2 14
So, by multiplying 5 and 7 by 2, 10/14 is another fraction that is equal to 5/7. Here's some more possible answers if you need them...
<u>5 x 3</u> = <u>15</u>
7 x 3 21
<u>5 x 4</u> = <u>20</u>
7 x 4 28

It’s a strong relationship. I had statistics last year. The closer it is to 1, the stronger the relationship is, the closer to zero it is, the weaker the relationship is.
A + b = 147....a = 147 - b
5.85a + 4.40b = 786
5.85(147 - b) + 4.40b = 786
859.95 - 5.85b + 4.40b = 786
-5.85b + 4.40b = 786 - 859.95
- 1.45b = -73.95
b = -73.95 / -1.45
b = 51 <== she used 51 lbs of type B coffee
